From what I've read of the specs Parallels should allow for a 64 bit Solaris guest. I'm currently using the trial version of Paralles 4.0 on a Mac Pro. Everytime I install Solaris though I seem to get the 32 bit version and not the 64 bit version. Is there something I am doing wrong? Does perhaps the trial version not support 64 bit guest OSes? Is there a setting I should check to enable 64 bit? I want to test Pro/Engineer Wildfire 3.0 on a Solaris guest on a Mac host. Pro/E It requires a 64 bit OS and OpenGL support. First things first though I need 64 bit support.
